The best time to seed your lawn is in early spring. This is the time that most homeowners want to do their seeding because grasses are dormant and easier for you to control. In addition, there should be a good amount of moisture at this point as well as no snow on the ground. It may also be beneficial by mid-May or early June depending on how much rain has fallen over the winter months prior to seeding. If you live where it snows during the winter months, wait until after May 1st before planting seeds into your lawn!
